Moramo dostaviti ugovor o najmu.

Moramo means we must / we have to.

Its base form is morati = to have to / must.

So:

• ja moram = I have to
• ti moraš = you have to
• mi moramo = we have to

In this sentence, moramo already tells you the subject is we, so Croatian does not need a separate word for we.

Because it follows the modal verb moramo.

In Croatian, after verbs like morati (must / have to), the next verb usually stays in the infinitive:

• Moramo dostaviti... = We have to submit/deliver...
• Moram ići. = I have to go.
• Moraju raditi. = They have to work.

So dostaviti is not conjugated here because moramo is the verb carrying the tense and person.

Dostaviti usually means to deliver, to submit, or to provide, depending on context.

In a document/administrative context, it often means:

• submit
• hand in
• provide officially

So in this sentence, dostaviti ugovor o najmu would most naturally mean something like submit the lease agreement or provide the rental contract.

Because ugovor is the direct object of the verb dostaviti.

The noun ugovor is masculine inanimate. In Croatian, the accusative singular of many masculine inanimate nouns is the same as the nominative singular.

So:

• nominative: ugovor
• accusative: ugovor

That is why you see:

• dostaviti ugovor = to submit the contract

If it were a masculine animate noun, the accusative would usually look different.

Literally, it means contract about lease/rental.

More naturally in English:

• lease agreement
• rental contract
• tenancy agreement (depending on context)

Breakdown:

• ugovor = contract, agreement
• o = about, concerning
• najmu = lease/rental (in the required case form)

So Croatian uses a structure that is a bit more literal than the most natural English phrasing.

Because the preposition o normally requires the locative case.

The noun is:

• najam = lease, rental

Its locative singular is:

• najmu

So:

• o najmu = about the lease / concerning rental

This is a very common pattern in Croatian:

• govoriti o problemu = to talk about the problem
• knjiga o povijesti = a book about history
• ugovor o najmu = contract about lease / lease agreement

Najam refers to rental or lease as a legal or contractual arrangement.

Depending on context, English translations can be:

• rental
• lease
• tenancy

It is not always exactly the same as the money paid as rent. For the payment itself, Croatian may use words like:

• najamnina = rent, rental fee

So:

• ugovor o najmu = lease/rental agreement
• najamnina = the rent you pay

Yes. Croatian often leaves out subject pronouns when they are clear from the verb ending.

Moramo already means we have to, so adding mi is usually unnecessary.

You could say:

• Mi moramo dostaviti ugovor o najmu.

But that would usually add emphasis, such as:

• We have to submit it (not someone else).

Without mi, the sentence sounds neutral and natural.

Yes. Croatian word order is more flexible than English word order.

The neutral order here is:

• Moramo dostaviti ugovor o najmu.

But you may also hear:

• Moramo ugovor o najmu dostaviti.
• Ugovor o najmu moramo dostaviti.

These versions can shift emphasis slightly:

• starting with Ugovor o najmu emphasizes the document itself
• keeping Moramo dostaviti... sounds like the most straightforward neutral statement

So the original sentence is a very natural default order.

This is about aspect, which is very important in Croatian.

• dostaviti = perfective
  focuses on completing the action
• dostavljati = imperfective
  focuses on the process, repetition, or ongoing action

In this sentence, Moramo dostaviti ugovor o najmu, the idea is that the contract needs to be submitted successfully / handed in, so the perfective verb dostaviti fits well.

Compare:

• Moramo dostaviti ugovor danas. = We have to submit the contract today.
• Svaki mjesec dostavljamo izvješća. = Every month we submit reports.

Yes. The exact English translation depends on context.

Dostaviti can mean several things in English:

• submit
• deliver
• provide
• send in

If this is about paperwork for an office, landlord, bank, or government authority, submit is often the best translation.

If the context is more general, provide may also work well.

So the Croatian sentence can be understood as:

• We have to submit the lease agreement
• We need to provide the rental contract

Both can be correct depending on the situation.
